The genus Cymatoceras (Nautilida) in the Lower Cretaceous of the Atacama Basin, northern Chile

Fragmentary remains of nautilids assigned to the genus Cymatoceras Hyatt, found in Barremian strata at the Atacama Basin, northern Chile, are described. The specimens can be divided into two taxa: Cymatoceras sp., from the late Upper Barremian, that has a poor preservation, but at the moment its orn...
